I like these changes, but where is the Jussi currently drawing data from?

I believe Hivemind isn't ready yet, and wasn't easily able to understand which of the other sources are being used for what.

I tried running the docker SBDS as this seems very useful to me, but the documentation isn't really there yet, I couldn't easily see the DB schema, and getting the data as checkpoints required Amazon S3 permissions I don't have. Are there any public sources for this checkpoint data?
